Ventura County Fire Department(THOUSAND OAKS, Calif.) — Two fast-moving wildfires that exploded in the hills of Southern California have forced thousands of evacuations, including the entire city of Malibu and a sprawling naval base.

The largest of the two blazes, the Woolsey Fire, grew to more than 70,000 acres on Saturday after spreading south from Simi Valley in Ventura County to Agoura Hills in Los Angeles County, where the flames jumped the 101 Freeway and continued burning toward the Malibu area. That stretch of the freeway was shut down in both directions on Friday.

The massive blaze was still zero percent contained Saturday morning, though hundreds of firefighters were working around the clock to quell the flames, according to the Ventura County Fire Department.

Two people have been found dead in an area of Los Angeles County where the Woolsey Fire is burning. Autopsies will determine whether the circumstances of the deaths were fire-related, according to the Los Angeles County Sheriff’s Department.

Late on Friday, President Donald Trump declared a state of emergency for California, freeing up federal resources to supplement local response efforts to combat three major wildfires blazing across the state. The declaration allows the U.S. Department of Homeland Security and the Federal Emergency Management Agency (FEMA) to coordinate disaster relief efforts to help alleviate the hardship and suffering caused by the emergency on the local population, provide support for emergency measures and free up federal resources.

But on Saturday morning, Trump threatened to pull federal funding for California wildfires if the state didn’t “remedy” the situation.

About 250,000 residents in Ventura and Los Angeles counties have evacuated or are in the process of evacuating, including a mandatory evacuation for all of Malibu, according to the Ventura County Fire Department. No evacuation orders have been lifted.

Pepperdine University in Malibu ordered its students and faculty to shelter in place Friday night, while the rest of the city was evacuating. The school lifted the shelter-in-place order Saturday morning but closed its offices and cancelled all classes and events on its Malibu and Calabasas campuses through Tuesday.

Andrew Benton, the president of Pepperdine University, later explained that the school, in cooperation with the fire department, has planned to shelter in place during these situations since 1993, after dangerous brush fires threatened its Malibu campus in 1985.

The Woolsey Fire has damaged or destroyed a number of structures, including celebrity homes and a legendary Hollywood film set.

Caitlyn Jenner posted an Instagram video on Friday, saying she had evacuated to a safe house but wasn’t sure what had become of her residence in the Malibu hills.

Lady Gaga, Mark Hammill, Kim Kardashian West and her sister Kourntey Kardashian also reported via social media they they have fled their homes due to the wildfires.

Meanwhile, the Woolsey Fire burned down a portion of Paramount Ranch in Agoura Hills known as “Western Town,” where hundreds of movies and television shows, including HBO’s “Westworld,” have been filmed, dating back to the 1920s.

Authorities have described the blaze as a very dangerous, wind-driven inferno.

Conditions were only expected to worsen over the weekend, with extremely critical fire danger warnings issues for the hills around Los Angeles. Wind gusts could reach 60 mph and relative humidity could be as low as 3 percent in Southern California, creating an environment for the flames to rapidly spread.

The Woolsey Fire ignited Thursday afternoon in Simi Valley, northeast of Thousand Oaks, not far from where a mass shooting claimed at least 12 lives late Wednesday night.

A smaller blaze, the Hill Fire, ignited around the same time Thursday in the Santa Rosa Valley area of Ventura County, northwest of Thousand Oaks. The fire was burning an area of about 4,500 acres on Saturday morning, as firefighters increased the containment level to 25 percent.

Several areas were under mandatory evacuation orders, including the Naval Base Ventura County’s facility in Point Mugu, located near Oxnard, according to the Ventura County Fire Department. Authorities had warned the flames could potentially spread all the way to the Pacific Ocean.

The governor-elect of California, Gavin Newsom, on Friday issued an emergency proclamation for Ventura and Los Angeles counties due to the Woolsey and Hill fires.

Meanwhile, a wildfire has laid waste to entire neighborhoods in Northern California.

Several people were found dead Thursday in the torched town of Paradise, which has been almost entirely decimated by the Hill Fire, authorities said.
